N atmc and Object of the I mention.

Description of the Drawing.

To enable others skilled in the arts to which it appertains to make anduse my invention, .l will proceed to describe its construction andoperation with reference to the drawing.

Figures 1 and 2 are longitudinal sections of a gas-burner made accordingto my invention, and the smaller figures are transverse sections made,respectively, on the dot-ted lines through their centers. v y Y Theburner tube or barrel a, which screws upon the gas-pipe, is made with aninternal flange, b, through which is drilled a series of holes thatcorrespond in position wit-ha similar series of holes in the flange c ofthe nib d. The tip or nib has a spur, c, that projects through a slot inthe barrel of the burner, by which itmay be moved radially to afford afree passage for the gas through the holes; or it may be moved to 'closethe holes entirely, or regulated at any intermediate point to adjust theiiow of gas through them, as may bc required to feed the iiame afterbeing diffused through the annular opening that surrounds the ame.

The tip may be of lava, cement, vor any other material that admits ofits being moved slightly to adj ust a series of openings at its base.The ange on the tip must close the slot in which the spur works toprevent the admissionv of air. By this arrangement the supplementarysupply of gas may be adj usted without appreciably affecting theposition of the iiam'e.
